The world's first ± 1,100 kV transformer was developed for China's High Voltage Direct Current (HVDC) transmission project and has the highest transmission voltage and has recently passed type testing.
This HVDC transformer has been developed, manufactured and tested by Siemens in its transformer factory in Nuremberg, and is the first of a total of seven ±1,100 kV transformers that Siemens and a partner company are building for what is currently the world’s largest HVDC transmission system, the manufacturer stated in a press release.
This type of transformer is a single-phase unit with a transmission capacity of 587.1 MVA. The transformers are being built in a network of Siemens factories led by its Nuremberg plant, in cooperation with its factory for HVDC transformers in Guangzhou, China, and another Chinese partner.
The transformers will be installed in the Guquan converter station of the HVDC link between the Chinese cities of Changji (Xinjiang) and Guquan (Anhui). This is the world’s most powerful HVDC transmission system in terms of transmission capacity, voltage and length.
The world's largest high-voltage DC link - that is, transformers - will be commissioned in 2018.
